Kaneiko 1:1 Contra Angle Low Speed Dental Handpiece

The Kaneiko 1:1 low-speed contra-angle handpiece is designed for controlled restorative, finishing and preventive dental procedures. Its direct-drive 1:1 transmission transfers the connected air motor speed directly to the handpiece, supporting smooth operation at speeds up to 40,000 rpm. An internal water spray helps cool the bur and treatment area, while the ceramic ball bearing supports stable rotation and precise handling. Choose between a fibre-optic Black Nano Titanium version or a non-optic stainless steel version to match your clinical setup.

Fibre-Optic Black Nano Titanium Version

The fibre-optic version features a Black Nano Titanium body and light transmission toward the treatment area for improved visibility. Its 1:1 direct-drive transmission, internal water spray and RA latch-type bur compatibility support controlled cutting, finishing and polishing during routine low-speed dental procedures.

Non-Optic Stainless Steel Version

The non-optic version features a durable stainless steel body and provides the same 1:1 transmission, internal water spray and RA latch-type bur compatibility without fibre-optic illumination. It is suitable for dental units and air-motor systems that do not require light transmission.

Internal Water Spray

The integrated internal water channel directs cooling water through the handpiece toward the bur and treatment area. This supports controlled temperature management and improved visibility during compatible low-speed procedures.
